🐛 bug - add referrer in creation

[pYassine]

No description provided.

[revu-bot]

This PR adds referrer validation during user creation, which is a good security improvement. However, there are critical issues with response handling patterns in the controller that need to be addressed. The controller mixes direct response handling with return values, creating inconsistent API behavior.
